PRINCE Harry might be tying the knot with girlfriend Meghan Markle, a close friend of the royal seems to have confirmed.

The Sun reports, Kirstie Ennis, a former US marine and Paralympic hopeful, let it slip that a wedding might be on the cards when quizzed by reporters about attending the ceremony.

When pressed for more information she immediately “pleaded the fifth” — a reference to the Fifth Amendment of the US Constitution: the right to remain silent — perhaps realising she had given too much away.

Her mum is therapist and yoga instructor Doria Radlan and her dad is Emmy-winning lighting director Thomas W Markle.

The source added: “Meet the Markles tells the story of some of Meghan’s ancestors and how she and Harry met.

“The film also considers her possible future role in the royal family.”

It should air later this year.

Markle, 35, appeared alongside her castmates from Suits at a script reading at the ATX Television Festival in the Paramount Theater in Austin, Texas.

The Suits cast did a live table read of their pilot episode, to celebrate Suits’ upcoming 100th episode.

When Markle was asked whether she had hopes of marrying Prince Harry though, things went silent as she did not reply with an answer.

She reportedly smiled instead, and said nothing, the Mail Online reports.

While Markle didn’t do any interviews at the event, her Suits co-star Patrick J. Adams told Entertainment Tonight she is “so happy” with her royal romance.

“Meghan and I have been such good friends for years now and to see her so happy is great. She’s super excited,” Adams told ET. “I’m super happy for her and she’s been such a pro in this season and it’s going so well.”

The star was spotted leaving Toronto, Canada, for Austin Texas, with a copy of last week’s edition of The Economist that was focused on the UK election and Brexit.

Prince Harry and Meghan Markle Are Getting SERIOUS - Is She the One?!1:14

Prince Harry's relationship with Meghan Markle has reportedly gotten more serious than any of Harry's previous relationships. Meghan has met his brother, Prince William and his wife Kate Middleton and their two children. Meghan has yet to meet the Queen, but we're thinking that meeting could be in the near future. It seems the couple is taking a major step forward, even buying a Christmas tree together and spending time with each other for the holidays. Could this be it? Is there another royal engagement around the corner? We certainly hope so!
